采用二维理论模型研究连续波扩散型氧-碘化学激光器的性能。假设主、副气流间在侧向压力不变的情况下进行混合和反应,采用有限差分技术来求解偏微分方程组,考察了比功率沿气流方向的变化以及O2（1⊿）浓度对比功率的影响。

A two-dimensional theoretical model for predicting the diffusional CW oxygen-iodine laser performances is presetted. The parallel mixing at constant lateral pressure between a pair of primary and secondary streams is assumed. A set of parabolic partial differential equations are solved using the finite-difference techniques. The change of specific power with flow direction and the effect of the concentration of O2(1) on specific power are studied.
